# Kedo-S / Kedo-S Plus

Dedicated pediatric systemMixed first-party / secondary record

Official Kedo material confirms the product family and current catalog. The original D1/E1/U1 design is primarily described in the 2017 case report, and Kedo's first-party generation chronology is internally inconsistent: the homepage still says five generations while the catalog also sells Nano Plus.

## Protocol

1

### 1\. Canal Assessment

Evaluate canal anatomy with radiograph. Establish patency with #10 K-file.

2

### 2\. Glide Path

Create glide path with #15 K-file to working length.

3

### 3\. Kedo-S: Canal-Specific File Selection

D1 (#25, Red) for narrow canals (MB/ML/DB). E1 (#30, Blue) for wide canals (distal/palatal). U1 (#40, Black) for anterior teeth. 150-300 RPM, 2.2 Ncm, brushing motion.

4

### 4\. Kedo-S Plus: Single-File Protocol

P1+ for posterior (molar canals). A1+ for anterior teeth. 250-300 RPM, 2.2 Ncm.

5

### 5\. Irrigation

NaOCl between files. 17% EDTA gel as lubricant during instrumentation.

6

### 6\. Obturation

Metapex or ZOE-based material.

## Clinical Tips

- •Original Kedo-S: 150-300 RPM, 2.2 Ncm. Plus/Nano Plus: 250-300 RPM, 2.2-2.4 Ncm
- •Apply light apical pressure with brushing motion
- •Color coding: D1=Red (narrow), E1=Blue (wide), U1=Black (anterior)
- •Advance in short movements (2-3mm)
- •Do not force beyond the apex

## Warnings

- ⚠Do not advance beyond the apex due to physiologic root resorption
- ⚠Do not apply excessive torque
- ⚠Dentin walls are thin - advance carefully

## Clinical Notes
